How to Use Blueprints in Fallout Shelter
Blueprints in Fallout Shelter are essentially plans for crafting new rooms or upgrading existing ones. Once you've got a blueprint, head over to the area where you'd like to build or upgrade. If it's a new room, you'll find it unlocked in the build menu. For upgrades, click on the room you want to improve, and if you have the required blueprint, you'll see an upgrade option. Make sure you have enough caps; those upgrades aren't free!

Just tap on the build menu, and if you got a blueprint, it’s party time - that room is ready to glow up or show up in your Vault. Make sure you’re not broke in caps though, or it’s back to the wasteland grind.
